Specification of Letters Patent;

Patented Dec. 31, 1918.

Original` application led April 29, 1915, Serial No'. 24,628. I Divided and this application filed February 12,

1917. Serial No. 148,103.

JTo all'whom it may concern:

. NER and ROBERT H. MILLER, citizens of the United States, residing, respectively, at New York, in the county of New York, and -State of New Yorlnand city'r of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Sectional Elbows for AshfConveyers, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming 'a part of this specification.

Our invention relates to conveyer systems such as are used for conveying ashes; our present invention being particularly concerned with the construction of an im roved sectional elbow which is adapted to form a part-of the conduit of such an ash conveyer system.-

This application is divisional of our co- 'pending application 'Serial No. 24828, filed April 29, 1915.

In the accompanying drawings illustratingpur invention,

Figure 1 is a more.l or less diagrammatic representation of an ash conveyer system embodying the improvements of our inveny tion.

Fig. 2 is a vertical sectional view of the sectional elbow to which our present inven-v tion is particularly directed, and

vit being understood that portion 10 -of the conduit, which is shown broken away, leads to any suitable dischargepoint such as an ash hopper. The lower portion of the ver-l tical part 10 of the conduit is conveniently supported by up-rights 13, engaging with collar 14, encircling the conduit, as shown.

the conduit is connected to the horizontal portion 15 through an elbow indicated as a whole by reference numeral 16. The

Fig. 3 illustrates the elbow rear eleva-I Figs. 2 and 3. The elbow consists essentially of the curved inner portion 1'?, back 18 and the bottom 19. The back 18 and the bottom 19 are substantially straight and are secured to the curved inner portion 17 by means of lugs 20 and bolts 2l, as is clearly illustrated in the several views. The bottom v19 of the elbow has secured in it a removable jet 22 which is supplied with steam from any suitable source through a pipe 23. ylhe bottom 19 and back 18 are conformed to provide an opening in which is inserted a wear plate 24. The wear plate 24 is held `in position by -a spring bar 25, engaging with lugs 26 von the back-and bottom sections of .the elbow. While the bottom 19 is substantlally straight in its conformation, it has on its inner surface an inclined guiding face 29 for delivering ashes toward the steam jet atan angle. rThe face of the wear plate 24 is also preferably inclined to assist in guiding the ashes into the vertical portion -10 of the`conduit.

r1`he elbow 16, the details of which have just been described, connects the vertical part 10 of the conduit with the horizontal .part 15, which we may state is provided 'elbow 16 is illustrated in more detail in sin with a hopper 27, booster jet 28, etc.` Our Y present invention is, however, not particularly concerned with any part of the ash conveyer system except the elbow, illustrated in detail in Figs.; 2 and 3. In so far as-the otherl features of the system are concerned, it will suiice to say .that they are fully illustrated, described and explained in our co-pending application hereinbefore referred to.

It will be seen that the elbow hereinbefore described is particularly adapted for use in.

steam jet ash conveyer systems for the reason that any one of the severalparts of the elbow may readily be renewed if the same becomes worn.l vThe wear plate 24 which receives the greatest amount of wear is readily removable and may be removed or .re-

placed without disturbing the other parts of the elbow. Moreover, the back and bottom of 'the elbow may readily be removed without disturbing the other parts of the elbow or pipe line.

Having thus described our invention what.

2. An elbow for ash conveyers comprisingy a curved inner portion, a removable bottom and a removable back, said bottom overlapping said back.

3. An elbow for ash conveyers comprising a curved inner portion, a removable bottom and a removable back, said bottom overlapping said back having an opening eX- tending therethrough. l

L1. An elbow for ash conveyers comprising a curved inner portion, a removable bottom, a removable back and a removable wear plate arranged in an opening in said bottom and back.

5. An elbow for ash conveyers comprising a curved inner portion, a removable bottom, a removable back, provided with an opening and an inclined guiding face adjacent to said opening.

6. An elbow for ash conveyers comprising a curved inner portion, a substantially straight bottom and a substantially straight back, said bottom and back'being removable and connected to said curved inner portion in planes at right angles to one another.

7. An elbow for ash conveyers comprising a curved inner portion, a substantially straight bottom and a substantially straight back, said bottom and back being removably connected to said curved inner portion in planes at right angles to one another, and said bottom overlapping said back and joined thereto in the plane of the joint between said bottom and said curved inner portion. j

In witness whereof, we hereunto subscribe our names this 24 day of January, A. D. 1917, and this 31st day ofJanuary, A. D. 1917, respectively.
